I was starting to architect my code, so that it could easily re-use connections to web sites, and also make it possible to have policies to avoid the platform turning into a tool for denial of service attacks. I think this will be a reason to only allow access to the service to webid authenticated users.
Yep!
That's the essence of the matter. Basically, Web 2.0 is a realm that's
utterly broken for this very reason, technically or commercially.
Without verifiable identity and resource access policies you cannot
integrate quality of service factors into a business model or
infrastructure technology.
Simple example, should every SPARQL endpoint give the whole world
unfettered access? Should every attempt at a Web-scale service require
the data center capacity of Google, Facebook, and friends?
FWIW -- Tim O'Reilly once told a W3C audience that (to him) Web 2.0 was
the moniker he used to express the construction and sustainability of
Google business model, which was fundamentally a function of scale :-)
